On climate and the economy
1. Climate action is not a budget buster or economy-wrecker. Shifting to a green economy could yield a direct economic gain of $26 trillion through 2030 compared with business-as-usual. This could produce over 65 million new low-carbon jobs.
2. Significant investment in infrastructure is needed over the next 15 years, around $90 trillion by 2030. New infrastructure must be compatible with climate goals.
3. Investing in resilient infrastructure in developing countries could deliver $4.2 trillion over its lifetime. An investment of $1 in resilient infrastructure, on average, yields $4 in benefits.
4. More compact, connected and coordinated cities are worth up to $17 trillion in economic savings by 2050 and will stimulate economic growth by improving access to jobs and housing.
5. Sustainable agriculture and strong forest protection could generate over $2 trillion per year of economic benefits, create millions of jobs and improve food security, while delivering over a third of the climate change solution.
6. Doubling global renewable energy capacity by 2030 could save the global economy between $1.2 and $4.2 trillion each year, largely due to a massive reduction in costs from pollution.
7. Putting a price on carbon and phasing out fossil fuel subsidies could raise $2.8 trillion that could be reinvested in public priorities.
8. In 2020, G20 governments committed $233 billion to activities that support fossil fuel production and consumption, compared with $146 billion to renewable energy, energy efficiency and low-carbon alternatives such as cycling and pedestrian systems.
9. Better water management could improve economic growth rates in some regions by up to 6 per cent.
10. The costs of adapting to climate change in developing economies may be up to $300 billion by 2030. But investing in resilience may cut post-disaster intervention costs by at least half.
