The 21st Conference of Parties (COP) took place in Paris in December and delivered a substantive agreement to tackle climate change on a global level. Philip Pascall, chair of ICE’s Energy Expert Panel, explains the main points of the agreement and what it means to civil engineering
In our November 2015 blog we considered what might be agreed at the COP21 Conference in Paris. Now that it has happened, you could say that it has delivered an agreement to agree. That is, the Parties agreed to work out what to agree in the future. Pledges to date still fall far short of achieving less than 2°C temperature rise.
However, 195 nations committed to legally binding processes towards limiting global temperature rise this century to well below 2°C. Clear intent was underlined by the largest ever gathering of heads of state (including Obama and Cameron) at the opening ceremony. So, the agreement is substantive.
The 21st Conference of the Parties (COP) to the United Nations Framework Convention on Climate Change (UNFCCC) was held in Paris in December 2015. The Conference reached a global agreement on action on climate change. Although inevitably short of what some stakeholders were seeking, the agreement is a genuine step in managing climate change. It will have a major influence on infrastructure and the built environment in the decades to come.
Three elements make up the overall "Paris Outcome":
Overall, the agreement is a 'hybrid' between a mandatory top-down, rules-based system and a bottom-up system of voluntary pledge and review of commitments to act.
The Paris Agreement marks a genuine turning point in global action on climate change. For the first time, all countries are committed to take action on both climate mitigation and adaptation. The NDC process establishes a common framework for delivering mitigation action, another first.
However, current intended NDCs will only limit the global temperature increase to approximately 2.7°to 3.5°C. Long term success will depend on the Parties taking further actions to close the gap to the 2°C target and below. Paris is best viewed as the start of a new global journey. The world now needs to press on with the major tasks ahead.
Delivery of NDCs and action on adaptation will result in a significant shift in emphasis for infrastructure and the built environment. For example, renewables and other low carbon energy sources will need to make up the great majority of energy supply by 2030 in the major economies. Existing initiatives on low carbon energy and energy efficiency will need to accelerate substantially.
Governments and investors will need to manage an orderly transition away from a fossil fuel dominated economy, while minimising stranded assets and negative impacts on workers. As an early example of the new perspectives that are needed, the G20 has established a taskforce on the implications of climate policy on financial stability, which will report in 2016. Ahead of COP21, all international development financing institutions agreed to align their financing with the Paris climate goals.
The new international emphasis on adaptation and resilience will also have a profound effect on the planning and management of infrastructure. There will be increased emphasis on the incorporation of future resilience to the increasingly extreme effects of climate change.
The Energy Secretary, Amber Rudd, said that the UK is "absolutely committed to this deal and making sure we deliver on it" (BBC Andrew Marr show, 13 Dec 2015). The UK has already done a lot, for example being the first country to enact legislation to reduce carbon emissions (Climate Change Act 2008) and to announce an end date to electricity generation from coal.
Worthy of note, Amber Rudd and team reportedly worked round-the-clock in pursuit of the deal in Paris (James Murray, Business Green, 14 Dec 2015). However, concerns are raised by the present Government's withdrawals and reductions of support for renewables and low carbon energy without warning, the signs that we will miss interim carbon reduction targets (e.g. for heat and transport in 2020) and the dearth of present energy policy (many policies having expired at the end of 2015). Nothing much has been forthcoming from Government since the announcements just after COP21.
Whilst the Energy Secretary insists that value for money and cutting emissions do not need to be separated, it would be really helpful to see long-term stable policy that shows how the UK will continue to make progress in line with the Climate Change Act, the Carbon Plan and of course the Paris agreement. Government frequently makes clear that it looks to competition and the private sector to achieve affordability, security of supply and decarbonisation (the energy "trilemma"). That being so, it is critical that developers and investors have confidence in Government policy.
Though civil engineers are already at the heart of both climate mitigation and adaptation, the Paris agreement will have direct and profound effects on the practice of civil engineering. Businesses and individuals all have a role to play, across all types of infrastructure and whatever their part in the life-cycle.
We have to improve the productivity of our industry hugely, as stated in the Government's Construction 2025 strategy. We need to innovate and collaborate. We have to eliminate waste. We must apply circular economy principles to optimise the carbon footprint of our projects. We must reduce energy use, improve energy efficiency and switch to low carbon sources. We need to design and build for resilience, minimising whole life cost and risk.
Through these and other means, we will find affordable solutions that both mitigate further climate change and adapt to the level of change that is now unavoidable.
