We usually speak of “the energy transition” or “the transition to a low-carbon economy.” But this expression comes short of the actual phenomenon. In fact, we are in the midst of an industrial revolution that is completely shaking up the energy industry and is bound to disrupt others as well, such as transportation.

The world’s oceans are being damaged by a constant and unprecedented accumulation of waste known as marine debris. The waste, mostly from effluent human activities, is brought to the oceans through currents and often carried far from where it originated.

Infrastructure resilience requires a coordinated policy response to ensure that infrastructure owners and developers have the incentive and capacity to integrate resilience. The framework is aimed at policy makers in OECD countries, but the underlying messages can be applied to other country contexts.

The OECD’s third Environmental Performance Review of Switzerland finds that despite being one of the greenest OECD countries in terms of energy supply, greenhouse gas emissions and domestic material consumption per unit of GDP, Switzerland urgently needs to address pressures on its biodiversity.

With marine biodiversity deteriorating at an alarming rate, there will soon be little left of the “octopus’s garden” that The Beatles once sang about. According to "Marine Protected Areas: Economics, Management and Effective Policy Mixes", pollution, overfishing and rising temperatures have damaged or destroyed 60% of the earth’s marine ecosystems.

The wet and verdant expanse of the Mekong Delta’s rivers and farms is a veritable rice bowl for the world. Not only do the region’s paddies produce half of Viet Nam’s rice crop yearly, the country is the world’s third largest rice exporter, with 17% of world exports of paddy rice. Our analysis identifies Viet Nam as facing the world’s fourth highest water risks for rice production.

This report investigates the effects of select climate policies, non-climate policies, as well as political economy factors on the decarbonisation of electricity in OECD countries from 2000 to 2015. Effects are analysed on the three phases of decarbonisation: (1) increasing the share of renewables installed, (2) increasing the use of renewables in generation, and (3) reducing the emissions from electricity.

At a time when nationalism is rising and individual countries are facing a growing array of threats, it is critical that we recognize a shared and unprecedented global challenge: We need to double our infrastructure in the next decade to meet global development needs, while achieving a systematic shift away from business-as-usual, carbon-intensive options to low-emissions, resilient infrastructure, to avoid catastrophic climate change.

Extended producer responsibility is a policy approach that aims to increase waste recovery and recycling. Extended producer responsibility systems aim to make producers responsible for the environmental impacts of their products throughout the product chain, from design to the end-of-life phase. This report focuses on free-riding of producers or retailers, which the fast expansion of online sales in recent years has been exacerbating.
