Natural gas releases fewer harmful air pollutants and greenhouse gases than other fossil fuels. That’s why it is often seen as a bridge technology to a low-carbon future. A new study by the Institute for Advanced Sustainability Studies (IASS) has estimated emissions from shale gas production through fracking in Germany and the UK. It shows that CO2-eq. emissions would exceed the estimated current emissions from conventional gas production in Germany.
Science has already given us a much better understanding of what we must do in order to leave our world intact for future generations. However, that understanding has had little impact on our collective behaviour. At the first Global Sustainability Strategy Forum in March 2019, 17 prominent scientists looked at how science can help bring about the changes we need to see. They have now published their findings in an IASS Discussion Paper.
About 80 per cent of current CO2 emissions are caused by the member states of the G20. So it’s clear that they have a particular responsibility to reduce greenhouse gas emissions and encourage a shift to renewable energy. The leaders of these countries now need to act on that responsibility at the G20 Summit in Osaka on 28 and 29 June.
The U.S. and Germany are moving in fundamentally different directions with their energy policies. Germany has embarked on its “Energiewende,” an energy strategy based on renewable energy and energy efficiency as well as the phase-out of fossil fuels and nuclear energy. It is an important building block in the country’s climate protection endeavors. The U.S. under the Trump administration has abandoned its national and international climate commitments. It is pursuing an “Energy Dominance” strategy that seeks to expand the production of U.S. coal, natural gas, and oil. This strategy marks a significant departure from the Obama administration, which pursued a climate action plan focused on fostering clean energy in the U.S. and abroad.
Several countries’ national determined contributions (NDCs) highlight climate finance as a precondition for the ambitious action needed to achieve development paths compatible with limiting global warming to 1.5°C in 2100. Many hopes have been pinned on new market mechanisms in this context, but the trade-offs demanded by carbon trading schemes continued to be hotly debated at the UNFCCC last week, not least due to their political and economic implications.
In the upcoming days Japan will hosts its first ever G20 Summit. As the main contributers to global warming, the G20 states agreed 2009 on a phase out plan of fossil fuel subsidies. Ten years later the failure of the G20 to act on global warming is evident: around $63.9 billion was spent by G20 countries this year to develop coal industries in the global south.
