Developing countries can prosper without increasing emissions

The Conversation - Fri, 2017-09-22 05:40

One of the ironies of fighting climate change is that developed countries – which have benefited from decades or centuries of industrialisation – are now asking developing countries to abandon highly polluting technology.

But as developing countries work hard to grow their economies, there are real opportunities to leapfrog the significant investment in fossil fuel technology typically associated with economic development.

This week, researchers, practitioners and policy makers from around the world are gathered in New York city for the International Conference on Sustainable Development as part of Climate Week. We at ClimateWorks will be putting the spotlight on how developing countries can use low- or zero-emissions alternatives to traditional infrastructure and technology.

Developing nations are part of climate change

According to recent analysis, six of the top 10 emitters of greenhouse gases are now developing countries (this includes China). Developing countries as a bloc already account for about 60% of global annual emissions.

If we are are to achieve the global climate targets of the Paris Agreement, these countries need an alternative path to prosperity. We must decouple economic growth from carbon emissions. In doing so, these nations may avoid many of the environmental, social and economic costs that are the hallmarks of dependence on fossil fuels.

This goal is not as far-fetched as it might seem. ClimateWorks has been working as part of the Deep Decarbonization Pathways Project, a global collaboration of researchers looking for practical ways countries can radically reduce their carbon emissions – while sustaining economic growth.

For example, in conjunction with the Australian National University, we have modelled a deep decarbonisation pathway that shows how Australia could achieve net zero emissions by 2050, while the economy grows by 150%.

Similarly, data compiled by the World Resources Institute shows that 21 countries have reduced annual greenhouse gas emissions while simultaneously growing their economies since 2000. This includes several eastern European countries that have experienced rapid economic growth in the past two decades.

PricewaterhouseCoopers’ Low Carbon Index also found that several G20 countries have reduced the carbon intensity of their economies while maintaining real GDP growth, including nations classified as “developing”, such as China, India, South Africa and Mexico.

‘Clean’ economic growth for sustainable development

If humankind is to live sustainably, future economic growth must minimise environmental impact and maximise social development and inclusion. That’s why in 2015, the UN adopted the Sustainable Development Goals: a set of common aims designed to balance human prosperity with protection of our planet by 2030.

These goals include a specific directive to “take urgent action to combat climate change and its impacts”. Likewise, language in the Paris Climate Agreement recognises the needs of developing countries in balancing economic growth and climate change.

The Sustainable Development Goals are interconnected, and drawing these links can provide a compelling rationale for strong climate action. For example, a focus on achieving Goal 7 (Affordable and Clean Energy) that also considers Goal 13 (Climate Action) will prioritise low or zero-emissions energy technologies. This in turn delivers health benefits and saves lives (Goal 3) through improved air quality, which also boosts economic productivity (Goal 8).

Therefore efforts to limit global temperature rise to below 2℃ must be considered within the context of the Sustainable Development Goals. These global goals are intrinsically linked to solving climate change.

But significant barriers prevent developing countries from adopting low-emissions plans and ambitious climate action. Decarbonisation is often not a priority for less developed countries, compared to key issues such as economic growth and poverty alleviation. Many countries struggle with gaps in technical and financial expertise, a lack of resources and inconsistent energy data. More fundamentally, poor governance and highly complex or fragmented decision-making also halt progress.

It’s in the best interest of the entire world to help developing countries navigate these problems. Creating long-term, lowest-emissions strategies, shaped to each country’s unique circumstances, is crucial to maintaining growth while reducing emissions. Addressing these problems is the key to unlocking the financial flows required to move to a just, equitable and environmentally responsible future.

Assumed safety of widespread pesticide use is false, says top government scientist

The Guardian - Fri, 2017-09-22 04:00

Damning assessment by one of the UK’s chief scientific advisers says global regulations have ignored the impacts of ‘dosing whole landscapes’ and must change

The assumption by regulators around the world that it is safe to use pesticides at industrial scales across landscapes is false, according to a chief scientific adviser to the UK government.

The lack of any limit on the total amount of pesticides used and the virtual absence of monitoring of their effects in the environment means it can take years for the impacts to become apparent, say Prof Ian Boyd and his colleague Alice Milner in a new article.

A new cycling law won't make roads safer and could postpone laws that could | Peter Walker

The Guardian - Fri, 2017-09-22 00:35

Of the about 400 pedestrians killed a year in the UK an average of just two are hit by a bike. Enforcing speeding limits on the other hand could help prevent 250 deaths

So there is to be an “urgent” review into whether the law should be changed to target dangerous cycling. This follows a campaign by Matt Briggs, whose wife, Kim, was killed when she was struck by a bike ridden by the now-jailed Charlie Alliston.

The first thing to stress is that I understand completely why Matt Briggs feels the way he does. I’ve talked to him, and appreciate why charging Alliston under an 1861 law was unwieldy and caused long delays. Briggs is a thoughtful, intelligent man and I wish him well.

When media sceptics misrepresent our climate research we must speak out

The Guardian - Thu, 2017-09-21 23:09

Our climate paper underlined that strong action towards the 1.5C Paris goal is perhaps more valid than ever, but reading some of the media coverage you might think the opposite was true

On Monday, we published a paper in the scientific journal Nature Geoscience that re-evaluated how much carbon dioxide we can still afford, collectively, to emit into the atmosphere and still retain some hope of achieving the ambitious goals of the Paris climate agreement to “pursue efforts” to keep global temperatures to 1.5C above pre-industrial levels. The carbon budget we found, to yield a two-in-three chance of meeting this goal, was equivalent to starting CO2 emission reductions immediately and continuing in a straight line to zero in less than 40 years: a formidable challenge.

Formidable, but not inconceivable. The distinction matters, because if it were already completely impossible to achieve the Paris ambition, many might argue there was no point in pursuing those efforts in the first place – or that the only option left is immediately starting to cool the planet with artificial volcanoes.

Fight to protect natural resources has become too dangerous in the face of violence from state forces, private security groups and state-sponsored vigilantes, say groups from 29 countries across Africa, Latin America and Asia

Land rights defenders from 29 countries have written to the UN asking it to act against violent corporate and state-sponsored groups which they say are threatening their lives and trashing the environment.

Thirty nine grassroots groups from Africa, Latin America and Asia, many of whose leaders have been killed or forced to flee for protesting the theft of land, big dams mines and forest destruction, say their fight to protect natural resources is becoming too dangerous.

Country diary: Slowworm's escape from jaws of disaster

The Guardian - Thu, 2017-09-21 14:30

Blanchland, North Pennines Seemingly in a trance, the reptile lay outstretched on the road with predator bites near its head

When I was a child there was a sheet of rusting corrugated iron lying on the sunny bank of my grandmother’s allotment. If I lifted it quickly I could often find a slowworm resting underneath. It would lie there, startled by the sunlight for a moment, then glide away, like a flowing column of mercury, into the hedge.

I have been an inveterate lifter of rusty corrugated iron sheets ever since, but although they are well recognised hiding places for these elegant reptiles I’ve rarely been lucky.

Politics podcast: AGL chief economist Tim Nelson on what to do with Liddell

The Conversation - Thu, 2017-09-21 13:53

In the eye of the storm over energy policy is Liddell, an ageing coal-fired power station owned by energy giant AGL.

Prime Minister Malcolm Turnbull has twisted the arm of AGL chief executive Andy Vesey to take to the company’s board the proposition that it should extend the plant’s life beyond its scheduled 2022 closure, or alternatively sell it to an operator that would carry it on.

AGL chief economist Tim Nelson says the company is running the rule over both options but he argues preserving the power station may not be the best solution. “The decision is not just economic, it is also also a commitment on carbon risk.”

Nelson says the emissions profile of extending the life of coal-fired power stations is inconsistent with current commitments in AGL’s greenhouse gas policy and the government’s undertakings under the Paris climate accord. Add to that the hefty rehabilitation costs for 50-year-old Liddell and it seems “the numbers don’t add up”.

While AGL is reviewing government options, it is so far sticking to its alternatives for the site – repurposing it, or repowering it with zero-emissions technology.

But without a coherent policy framework it is hard to see an orderly transition in the energy market. Nelson says a clean energy target could fix the uncertainty, encouraging the replacement of old technology with a combination of renewables and “complementary capacity from flexible sources”.
