What is the difference between net zero and zero carbon?
We frequently hear the terms “net zero” and “zero carbon,” but what do they mean and how do they differ?
The goal of net zero is to “balance” or “cancel out” any carbon that we produce.
When the amount of greenhouse gas we create equals the amount that is removed, we have reached net zero.
The term “zero carbon” refers to the absence of any carbon emissions from a good or service.
One illustration in the context of energy production would be the production of electricity by a wind turbine.
If the market can only supply us with electricity from renewable sources, our goal is to be able to run Britain’s system carbon-free.
Running a zero-carbon grid is crucial to GB’s 2050 net zero goal.
There is a strong link between water management, reuse and recovery, as well as energy utilization, and the goal of achieving a net-zero carbon discharge footprint in future green cities.
To achieve net-zero GHG greenhouse gas emissions while producing electricity, organic solids and spent water should be co-processed and resources recovered.
The combined resource recovery capability of hydrogen-based energy recovery and transformation to electricity is proposed for green cities.
2020 has been a year of confusion and during this, we’re seeing transformation in action.
There has been an overwhelming cultural shift within side the manner we work, supported by the implementation of the innovative clarification, which opened quicker than all of us may want to have imagined.
How the water sector can lead the way to net-zero
The water industry is in a special situation.
A vital resource has long been managed by water operators, and a thriving economy’s water infrastructure is its foundation.
The world’s water utilities release the same amount of greenhouse gases (GHGs) as the shipping industry, making modern water systems significant contributors to global GHG emissions.
However, water utilities could quickly and significantly reduce their emissions at little to no cost, and they are already making a significant effort in this direction.
In reality, the decarbonization of the water industry may be among the fastest and serve as a model for others.
The way the sector is collaborating to get there is as follows:
Making firm, sector-wide commitments to reduce emissions
Leading utilities and stakeholders from across the water sector are joining the Race to Zero, the UN’s global initiative rallying sectors and regions to take immediate action to halve global emissions by 2030.
Water companies in the UK have almost halved operational emissions since 2011 through a combination of energy efficiency measures, renewable energy, and the production of biomethane from sewage treatment processes.
It’s a global trend: more than 65 water and wastewater utilities around the world have already set net-zero, carbon, and climate neutrality targets, including some of the largest utilities in the world.
By defining the destination, our sector is setting a firm direction of travel toward decarbonization.
Deploying affordable, high-efficiency technologies to make meaningful, early progress
In the race to zero, readily available technology, along with adjustments to the procedure, law, and practice, are a crucial and reasonably priced component of the road map.
According to analyses by Xylem and its partners, existing high-efficiency technology might allow water utilities around the world to reduce GHG emissions by 50% at little to no expense.
Consider using “smart” pumps, sensors for leak detection, and other digitally-powered tools to significantly cut the energy required for water treatment and transportation.
These opportunities for reduction are low-hanging fruit and, most importantly, don’t call for new technologies or carbon-pricing regulations.
Defining the pragmatic actions – processes, policies and practices – to get to net zero
One component of the solution is technology.
To advance quickly, establish accountability, lower the costs and risks of the transition to net zero, and unleash new advantages associated with emissions reduction activities, supporting systems, policies, and practices are required.
Experience in the water sector shows that the necessary elements for success are available right now: reasonably priced technology, expertise, money, collaboration and increasingly, regulatory incentives.
Furthermore, our experience demonstrates that significant gains may be achieved quickly, economically and with little risk by prioritizing the reduction of emissions.
What exactly is transformational innovation?
It is a type of innovation that could provide a critical shift toward new viability models that align with future goals.
It is the opposite of rising innovation, in which little extra changes help chip away at a larger aim.
Unless confronted with a seismic catastrophe such as a pandemic, disruptive innovation no longer occurs overnight.
It takes a significant collective effort, as well as a diverse collection of stakeholders, to encourage and pressure a shift in training.
Zero carbon strategy of the United Kingdom
In the United Kingdom, the water sector comes collectively around an innovation fund, which has a reason to catalyze this form of innovation.
There are precise regions of the sector, which are high-level for transformational innovation in 2021.
Firstly, there’s a readiness to interact with the net-zero carbon agenda, which means constantly driving down carbon releases throughout businesses.
The UK has hard national goals and integrates that with the current appearance of a water sector strategy.
Secondly, and that is a private one as I spend time withinside the rivers and seas around the United Kingdom, those open our bodies of water are becoming the highlight of innovation to reach ‘0 pollutions’.
For a variety of motives and legacy concerns, we still note untreated wastewater and polluted rancid achieving the environments and the watercourses.
I’d propose for this difficulty to be listed along with leakage in water networks, in which development in generation withinside the beyond few years has converted information and operations.
Impact of climate change
Now is the time to expand engagement on climate change at a worldwide level.
Countries are revising their climate change obligations in planning for the next UN Climate Change Forum, COP26.
These obligations, the Nationally Determined Contributions (NDCs), must be three times more determined to bound the global temperature rise to 2°C, and five times tougher to keep that limit to 1·5°C.
Zero short of net zero emissions by 2050 will keep us at 1·5°C this time.
Without stronger obligations, we are on track for warming up to more than 3°C, a change that is untenable for the health of many populations.
